:Product: 0110RSGA.txt :Issued: 2008 Jan 10 2202 UTC # Prepared jointly by the U.S. Dept. of Commerce, NOAA, # Space Weather Prediction Center and the U.S. Air Force. # Joint USAF/NOAA Report of Solar and Geophysical Activity SDF Number 010 Issued at 2200Z on 10 Jan 2008 IA. Analysis of Solar Active Regions and Activity from 09/2100Z to 10/2100Z: Solar activity was very low. No flares were observed over the past 24 hours. IB. Solar Activity Forecast: Solar activity is expected to be very low. IIA. Geophysical Activity Summary 09/2100Z to 10/2100Z: The geomagnetic field was quiet. The greater than 2 MeV electron flux at geosynchronous orbit was at high levels. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be mostly quiet for 11-12 January. Unsettled to isolated active conditions are expected on 13 January as a recurrent coronal hole becomes geoeffective. III.
